T all 20. mm it may concern Be it known that l, Emme a citizen of the United States, Litehfield. in the county of State of Minnesota, have invenlerl new and useful Improvements in Aeroplanes, of which the following is e specification.

This invention relates to aeroplanes, and its primary object is to provide a. simple, reliable e115. eilieient construction of aeroplane which shall be inherently self-balancing, both laterally and longitudinally.

A further object of the invention is to provide an aeroplane structure in which front and rear supporting; surfaces, each consisting of laterally-extending Wings, are arranged both fore and aft of a car or oer-- riage sustaining the load Weight. and are carried by clihedrally-angled heed and tail frames, whereby the points of support noon. the air, when ihe machine is in fli 'ht, a,- at a levei'above and equidisteirtlf in 011i, we rear of the load Weight, so that she resist once of the load Weight to deflection from its llOl'l ui position, as Well as the and longitudinal dihedral disposition the Wings, wiil result in self-righting swion in the event of the balance of the machine being; at any diseurheci unequal ir pressures upon. parts 0 s supporting so i The invention consists of is eonsirueiion combination and of parts herein fully described reference being liad to the drawings in which i'-- Figure 1 is o' from elem plane embodying in ii a side elereiion or top plan View of the plan View of the eorri tucliiial section throfl tion of the transverse seeiioii g in the practice emood fi; .rf my inve11- tioo, provide "f rane struoure 1 in 1e form 0; ii or plati oi" to receive s 1H] seax iii the viatoi' and pesse 5, if any th in motoii or mozors a (i the eoni-roi e ices which lASiJ very in number and arrangement aeoorelir to eharoeterand number of rudders employed. lire oi? this oer or carriage pszovi with suitable w, tosuppor'ithe eeiitrai portion of the meehme when. said machine is at resi", upon G.

2. An aeroplane including a central car or carriage, head and tail frames projecting upwardly and forwardly and upwardly and vrearvvardly, respectively, from said car or carriage, said frames being coextensive in dimensions and disposed at like angles to the of the head and tail frames. I In testimony whereof I afiix my signature in presence of two witnesses.
